For first-time cannabidiol (CBD) users, it is always a matter of confusion, and that of debate for regular users:
The questions are endless. But, before we can answer them, you need to first understand:
It is the cannabinoid composition, ratio or the spectrum in any CBD product that determines whether it is a full spectrum CBD, broad-spectrum CBD, or a CBD isolate. All CBD products available in the market must belong to any one of the above compositions or spectrums.
But how are they created differently?
CBD Extraction – Setting the Cannabis Strains Apart
In order to create a CBD product, the cannabinoids are extracted from cannabis plants, using different kinds of decarboxylation processes. These processes chemically remove a carboxyl group from the complex compounds (the cannabinoids) and release carbon dioxide. When cannabis is decarboxylated, a carbon atom is removed from a carbon chain.
Decarbing cannabis doesn’t just extract CBD; instead, it extracts all other compounds found in the plant – terpenes, flavonoids, and other cannabinoids.
All of these compounds are found in different proportions in different strains of the cannabis genus. Hence, the composition and the cannabinoid profile of the end-product depend on the particular strain of cannabis used in the extraction stage.
Hemp, which belongs to the Cannabis Sativa species, contains little to no THC. However, marijuana, which is also a Cannabis Sativa strain contains far higher levels of THC. In comparison, Cannabis Indica, contains equal proportions of CBD and THC.
Different strains are used by the manufacturing companies depending on the purpose or use – medicinal or recreational drug. Even after the extraction process, manufacturers can choose to refine the extract to ensure the presence of specific cannabinoids in specific proportions.
Isolate is the purest form of a compound, produced by extracting it individually, without it being in combination with other elements or compounds. It is created by isolating it from its usual environment and separating it from the usual compounds it is combined with.
In the case of CBD, the other compounds are the list of cannabinoids (mentioned earlier, terpenes, flavonoids, and fatty acids. CBD isolate products are available in crystalline solid or powder forms, containing at least 99% pure CBD.
Often patients, taking CBD to manage pain, ingest it orally or mix it with food items or drinks. You can also smoke or vaporize (with a vape pen) it like any other cannabis concentrate.
CBD isolate, being the purest form of CBD, is devoid of all other compounds found in cannabis, including terpenes, flavonoids, plant parts, and even other cannabinoids.
Pure CBD products are preferred for two main reasons:
CBD Isolate is generally extracted from hemp, as this strain of cannabis has no or negligible THC-content.
Full Spectrum CBD
In contrast to CBD isolate, a full-spectrum CBD extract contains all kinds of compounds that are naturally present in the plant, including all cannabinoids, including THC, terpenes , flavonoids  and essential oils.
CBD isolate was believed to be more effective than full-spectrum CBD until 2005 when this theory was contradicted by the authors of a study  that clearly displayed better outcome from full-spectrum CBD than CBD isolate.
The researchers from the Lautenberg Center for General Tumor Immunology in Jerusalem found that test subjects given full-spectrum CBD experienced higher levels of relief compared to those given pure CBD. Besides, it was also found that full-spectrum CBD offered better and more enhanced results with higher dosages, which wasn’t the case with pure CBD. With CBD isolate, increased dosages made no difference in therapeutic effect on the test subjects.
This brings us to the concept of “Entourage Effect” [4 & 5].
All cannabinoids (including CBD), terpenes, flavonoids, and essential oils – all of which are found in a full-spectrum CBD product – work in unison to magnify the therapeutic benefits of each individual compound. This effect is known as the Entourage Effect.
Proponents and advocacy groups, who support the use of full-spectrum CBD, believe that using or consuming substances in the form that nature intended them to be are, in fact, the best way to take them. For example, coca leaves aren’t dangerous until they are distilled and synthesized to create cocaine.
When all these compounds interact together with our body, their effects are boosted, making them more potent and bioavailable. In short, it is a synergistic effect on our system – just like teamwork!
In case of cannabis, it has been seen that the different compounds can amplify  each other’s chemistry, enhancing their effect on humans and animals alike and helping in addressing adverse symptoms more efficiently.
In fact, a lot of CBD advocates claim that the full-spectrum form is the most effective, no matter what the ailment, given that it has far higher bioavailability .
Interestingly, terpenes have some very significant benefits. Apart from giving cannabis its unique smell and flavor, these oily compounds offer a variety of benefits. Some of the most common terpenes in cannabis include:
Apart from their innate medicinal values, terpenes also have another very important role. They intensify the power of the cannabinoids, especially CBD. In order to retain these terpenes during the extraction process, the raw cannabis should never be heated up to 300°F.
Then, the question arises: If using full-spectrum extract is so great, why can’t we all use it? There are several hurdles  to overcome before everyone can have access to this holistic approach. They are:
Nonetheless, research is still on to gain a better understanding of the therapeutic benefits of whole-plant use of cannabis and how they interact with the body.
This variant negates the effects of THC while keeping the entourage effect intact. That is broad-spectrum CBD. This has the goodness of both a Full-Spectrum CBD and CBD Isolate product.
Like in a Full-Spectrum CBD extract, the other compounds found in cannabis plants – terpenes, flavonoids, essential oils, fatty acids, and several cannabinoids – are all preserved, but with one exception. Like in CBD Isolate, the broad-spectrum extract is completely devoid of THC.
Due to this, broad-spectrum CBD can deliver the enhanced benefits of the “entourage effect,” without the risk of psychoactive effects of THC.
Which Variant is Better and for whom?
If you are still confused about which variant to choose, take a look at the following comparative table that discusses the pros, cons and usability factors.
No THC, no risk of intoxication;
Generally safe, no risk of overdose;
Tasteless & Odorless;
Won’t test positive for THC
Does not produce the enhanced effects of the entire plant
Type of User
Who have been recommended to take especially high doses of CBD;
Who are sensitive to THC;
Who regularly undergo drug screening;
Who don’t like the taste of cannabis;
Full Spectrum CBD
Provides the complete benefit of cannabis plants (entourage effect);
Undergoes fewer processes
May have intoxicating, sedative and other adverse side-effects;
May show up on drug screening tests;
Strong natural flavor and smell
Who have been recommended a specific CBD: THC ratio;
Severe conditions on which CBD isolate has no effect;
Who live in areas where cannabis as a whole is legal
Broad Spectrum CBD

Who finds no relief from CBD isolate;
Who are sensitive to THC;
Who live in states with anti-THC laws;
First-time users can also try it safely
Final Thoughts on different types of CBD
CBD undeniably has quite a few therapeutic benefits on our body and mind. Given the above facts, it may be safe to say that, considering all variables in our life situations, broad-spectrum CBD is an easy and safe bet, although such products are quite rare.
While scientists are busy doing their part, users should always act responsibly – be wary of the law and ALWAYS consult a doctor before choosing any variant of CBD product.
It’s better safe and sorry!
